Stock 340 dyno tests?

All I will add is I ran 14.20’s with my stock 1972 (340) 4 speed duster with 3.91 gears. Self tuned by a 19 year old punk. Suck azz street tires
Not bad considering my Bone stock 86 Fox body runs 15s LOL! Its nice to know I will more than likely easily get more out of my 340 Swinger when I get it back on the road...:)
